microstructural evolution and chemical corrosion of electron beam wire feed additively Manufactured aisi 304 stainless steel
Journal of Alloys and Compounds, 2019Co-Authors: Yu S Tarasov, A V Filippov, N Shamarin, S V Fortuna, Galina G Maier, E A KolubaevAbstract:Abstract Using an electron beam wire-feed additive manufacturing three sets of Samples were obtained at different heat input levels. The Samples contained different amounts of vermicular δ-ferrite that depended on the heat input value used. Chemical corrosion tests were carried out to find out that the corrosion resistance of a Sample is determined by the δ-ferrite amount in it. High δ-ferrite content in the Sample obtained at medium used heat input value caused enhanced corrosion in the Cr-depleted austenite grains. Otherwise, when using the maximum heat input the additively Manufactured Sample contained the minimum amount of δ-ferrite and demonstrated the highest corrosion resistance as well as formation of a cubic crystallographic texture. No such texture was found in Samples grown at lower heat input values. In addition, no inter-granular corrosion induced open cracks have been observed on all Samples after 90° angle flexural test.

characterization of aa7075 aa5356 gradient transition zone in an electron beam wire feed additive Manufactured Sample
Materials Characterization, 2021Co-Authors: V R Utyaganova, A V Filippov, Sergey Tarasov, N Shamarin, D Gurianov, A V Vorontsov, A V Chumaevskii, S V Fortuna, N L Savchenko, V E RubtsovAbstract:Abstract A transition zone formed using electron beam wide-feed additive deposition of AA5356 on a AA7075 substrate was investigated for microstructure, composition, tensile strength microhardness and chemical corrosion resistance. The chemical composition of the transition zone was characterized by incrementally increasing content of Mg and decreasing contents of Cu and Zn. Microstructurally there was a transition from thick intergrain intermetallic network to uniformly distributed intermetallic particles. Phase composition of the zone was represented by coarse and fine Al-Mg-Cu-Zn particles, as well as FeAl ones and Mg2Si composite particles located at the columnar grain boundaries. Microhardness and tensile strength of this zone were higher than those of pure AA5356 deposited metal. Severe intergranular corrosion was observed on the surface of the transition zone. The intensity of corrosion inversely correlated with the Mg content.
